A local shelter is having an Adopt-a-thon for kittens and puppies. Kittens cost $50 to adopt and puppies are $75. The shelter made $1200 during the Adopt-a-thon event and adopted off twice as many puppies as kittens. Write and solve a system to find how many puppies and kittens were adopted
Answers
Answer:
Step-by-step explanation:
P=2K
50K+75P=1200, using P from above makes this equation become
50K+75(2K)=1200
50K+150K=1200
200K=1200
K=6, since P=2K
P=2(6)=12
So 12 puppies and 6 kittens were adopted.

Y= -6/5x-7 and y=2/5x+1
Answers
Answer:
x = -5
y = -1
Step-by-step explanation:
Y= -6/5x-7 and y=2/5x+1
then:
-6/5x - 7 = 2/5x + 1
simplify:
-8/5x = 8
divide both sides by 8:
-1/5x = 1
multiply both sides by 5:
-x = 5
x = -5
y = 2/5(-5) + 1 = -2 + 1 = -1
A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,
and (6q – 9) centimeters. Which expression represents the perimeter, in
centimeters, of the triangle?
Answers
Given:
A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,
and (6q – 9) centimeters.
To find:
The expression that represents the perimeter, in centimeters, of the triangle.
Solution:
We know that, perimeter of a triangle is the sum of its all sides.
[tex]Perimeter=(6p-7)+(7p-2)+(6q-9)[/tex]
Combining like terms, we get
[tex]Perimeter=(6p+7p)+6q+(-7-2-9)[/tex]
[tex]Perimeter=(13p)+6q+(-18)[/tex]
[tex]Perimeter=13p+6q-18[/tex]
Therefore, the perimeter of the triangle is represented by the expression [tex]13p+6q-18[/tex] centimeters.
A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters, and (6q – 9) centimeters.
To find:
The expression that represents the perimeter, in centimeters, of the triangle.
Answer:
-18+13p+6q

Robert bought a pair of shoes that was on sale for 30% off
the original price of $79.95. Which is closest to the sale
price of the pair of shoes?
Answers
Answer:
The sale price of the shoes is $55.96
Step-by-step explanation:
1: 30% of $79.95 is 23.985.
Which would round to $23.99.
Then subtract 23.99 from 79.95.
79.95-23.99= 55.96
On Sunday, the high temperature was 71° F, but on Monday it was 5° F lower. What was the percent change?
Answers
Answer:
The percent change is -7%.
Step-by-step explanation:
In order to find the answer, you can use the following formula:
Percent change=(New value-Old value/Old value)*100
New value=71-5=66
Old value=71
Now, you can replace the values on the formula:
Percent change=(66-71/71)*100
Percent change=(-5/71)*100
Percent change=-0.07*100
Percent change=-7%
According to this, the answer is that the percent change is -7%.

∠WZX = 57°
Step-by-step explanation:
Because it is a rectangle, ∠XYZ is 90°
∠XZY + ∠YXZ = 90
(5x - 8) + (x + 20) = 90
simplify:
6x + 12 = 90
subtract 12 from each side
6x = 78
divide both sides by 6
x = 13
∠WZX is complimentary to angle (x + 20)
∠WZX = 90 - (13 + 20) = 57°

how do you solve (7^-1)^-1 and 5^2 * 5^4 * 5^-3
Answers
Answer:
Step-by-step explanation:
exponents raised to a - power is an inverse function probably not the right word
a^-b = 1/(a^b) example 4^-2 = 1/(4^2) = 1/16
so (7^-1)^-1 is a double inverse which is back to the original number 7
inverted 7 twice
(7^-1)^-1 = (1/7)^-1 = 1/(1/7) = 7 trust me or use your calculator
since the coeffients are the same just add the powers... some exponent rule
5^2 * 5^4 * 5^-3 = 5^(2+4-3) = 5³
here is it written out
5^2 * 5^4 * 5^-3 = 5² × 5^4 × 5^-3 = (5×5) × (5×5×5×5) × (1/5×1/5×1/5)
5×5 × 5× (5×5×5 × 1/5×1/5×1/5) (5×5×5 × 1/5×1/5×1/5) = 1
5×5×5 = 5³
so
